1. (35 marks) Consider the external beam radiotherapy setup shown in the figure below. The x-ray point source emits a divergent beam towards the tissue. The source surface distance is 80 cm and the beam width at the surface is 8 cm. The linear attenuation coefficient of the tissue is 0.1 cm$^{-1}$ and the mass-energy absorption coefficient is 0.05 cm$^2$/g. The beam intensity at the surface of the tissue is 5 \times 10$^{-3}$ W/cm$^2$ and the beam is turned on for 10 s. Compute the following parameters for depths (d) of 0.1 cm, 5.0 cm, and 10.0 cm in the tissue: • beam width in units of cm, • intensity in units of W/cm$^2$, • and absorbed dose in units of Gy. Account for both beam attenuation and divergence in your calculations. Also use the above information and calculations to plot the percent depth dose (PDD) curve at d = 0, 0.1, 5, and 10 cm.
